Draw on a cylinder

Hello !
Did someone have a tutorial to draw on curved shapes ?
I would like to make some textured roller.

Thank you

Right now, about all you can do is draw on a plane and then project onto the cylinder.

If I may expand on what @TheBum has stated.
Here I projected a zigzag onto the cylinder, rotated the cylinder and projected again.
Then I colored the zigzag area and extruded it outward and used Move-Rotate to give it an angle.
Then I Copy-Rotated the cylinder twice and did a Union.
This may give you some ideas on what you would like to do.


Thank you both ! I’ll have to train a little but it can be cool :+1:
